Does the ISO drafting standards actually say not to use trailing (insignificant) zeros on dimensions? If so, where?

This is easy to find in ASME Y14.5-2009, but I cannot seem to find it in the ISO standards, like 129.

CH, you are right.
I can find out the statement that both “comma” and “point” are allowed, please ref to the attached for details. The snapshot is from Alex’s ISO Geometrical Tolerancing Reference Guide page 12, unfortunately I can’t find out any statement regarding to the trailing zero from this reference guide.

CH, SeasonLee,
Stars to you for helping me on "comma vs. point" thing.
 
"I don't think I will miss it"

I've noticed complaints about using a comma instead of a decimal, but don't recall anything so far about not using commas a separators. I personally find the space instead of a comma to be ambiguous, and would rather see no separator rather than a space.

Basically, that’s exactly what they say:
“Use no separator, but if you cannot do without one, use space”
